“…However, a low-tech NZEB definition does not need to be based on stringent comfort models that do not consider the outdoor temperatures. There is a serious opportunity to develop new definitions and concepts for NZEB in non-industrial countries that integrate more tolerant adaptive comfort models, reflecting the socio-economic status [1,30,33]. The use of adaptive comfort models for NZEB can significantly reduce energy consumption and make it easier to achieve annual energy neutrality.…”

The potential of carbon dioxide emissions mitigation in the building sector can be achieved through energy policies, progressive goals, and support systems to attain sustainable constructions that guarantee the reduction of emissions. Net-Zero Energy Buildings (NZEB) is a concept that allows moving forward to neutralize buildings’ carbon emissions. This has been demonstrated by more industrial countries which have set goals and challenges to progressively approach an energy neutrality balance for buildings. Therefore, the target of this research is to define a framework for a new standard to reach NZEB in Chile. Firstly, an exhaustive review of the energy policies, NZEB definitions, and components of an NZEB system took place. Secondly, focus group discussions with local and international professionals from the building sector were organized to define a vision, opportunities, and potential measures with a focus on policies, to implement and develop local technologies for NZEB buildings in Chile. The study identifies the need to advance public policies to achieve an integrated policy for the implementation of energy neutral concept buildings. Finally, the paper presents a NZEB standard framework, including key performance indicators and suggested performance metrics thresholds.

“…Experienced analysts may use a strategic model to frame the parameters of debate. For instance, they may treat the model as an opportunity to inform project stakeholders on recent research in adaptive comfort [22][23][24][25][26][27][28][29][30][31][32][33][34][35][36], advocating for natural ventilation principles to be incorporated into the schematic design. In such a case, the analyst may try to show the cumulative influence of passive design measures on the floating or free-running temperature; that is, how the interior temperature evolves without active thermostatic control.…”

The Optimal Tuning, within Carbon Limits, of Thermal Mass in Naturally Ventilated Buildings

What proportions should a thermally massive building have? How should the thermal mass be distributed? Should the "massing" change with the choice of material? This paper shows how to optimize the physical proportions of a building so that it synchronizes ambient heat exchanges in a natural feedback cycle. An internal mass is thermally coupled with buoyancy ventilation; the cycle is driven by the daily swing of outdoor temperature. Tripling up functions in this way—so that structural materials can reliably cool and power the ventilation for buildings—could help decarbonize the construction industry and provide an effective strategy for adapting to life-threatening heatwaves. Based on harmonic analysis, the method allows designers to thermally tune the form and mass of a building to meet chosen targets for temperature and ventilation in free-running mode. Once the optimal balance of exchange rates is known, design teams can proportionally vary the building height and ventilation openings against the surface area and thickness of an internal thermal mass. The possible permutations are infinite but parametrically constrained, allowing teams to fairly compare the functional and environmental credentials of different construction materials while they produce and evaluate preliminary options for organizing the exterior form and interior spaces of a building. An example study suggests that thin-shell structures of minimum weight, and even timber buildings, may be optimally tuned to produce ample ventilation and temperature attenuation.

One of the factors to enable energy efficiency in buildings is creating thermal comfort for the occupants of buildings so that the artificial vaporization is not required. The thermal sensation vote (TSV) is an indicator in analyzing the occupants’ satisfaction on the thermal comfort of their buildings. Some climate variables that relate to the TSV include air temperature, humidity, and wind speed. The three variables can be combined into a variable using a psychrometric chart. The combined variable is known as an effective temperature. The present research aims at analyzing the connection between effective temperature and TSV in vernacular houses in the tropical mountain and beach locations and comparing the results of the analysis. The quantitative method was employed in the research by measuring the variables of climate using a thermal measuring instrument. The TSV was measured with ASHRAE (American Standard of Heating, Refrigerating, Air-Conditioning Engineer)’s seven-point sensation scale. The measurement was carried out in transitional periods from the dry season to the wet season. Interpretation of graphs and charts was made for analysis based on the variable of effective temperature. The results of the research indicated that there was a connection between effective temperature and TSV. The effective temperature in vernacular houses in tropical mountain locations tended to be lower, and therefore the cool thermal sensation had the greatest percentage of TSV. Meanwhile, the effective temperature in tropical beach locations tended to be high, and therefore the warm thermal sensation had the greatest percentage. In a neutral scale, the percentage of TSV in tropical mountain locations was greater than that of TSV in tropical beach locations. Therefore, it is concluded that the occupants of vernacular houses in tropical mountain location felt more comfortable than those of vernacular houses in tropical beach locations.
